Wood Type

Real Wood That's Built to Take the Heat

All Thermory saunas start with 100% natural wood that's harvested and produced responsibly, guided by the highest standards for quality and sustainability.
All the wood species we select are ideally suited to withstand the rigors of regular sauna use. That means every time you step into a Thermory sauna, all you
notice is unequalled beauty and comfort.

The Right Wood

We look no further than the birthplace of sauna culture for beautiful Nordic softwood to craft your Thermory Barrel Sauna. Unlike cedar, which can become rough and unattractive over time, Thermory Nordic spruce’s proven rot resistance and ability to withstand the elements create the perfect marriage between outstanding design and structural integrity.

The Right Way

Our Nordic spruce is harvested exclusively in Scandinavia, a region celebrated for its responsible forestry practices. And wood is the only naturally renewable building material that doesn’t generate hazardous waste. So when you choose a Thermory Barrel Sauna you’re investing in the health of our planet. That’s why our mission is to “leave a lasting impact.”

Assembly

We pride ourselves on our attention to detail—right down to our installation guides. Your Thermory Square Sauna comes with pre-cut and pre-milled staves and cradles, so there’s no cutting necessary. In less than a day, you and a few friends can have your sauna fully constructed.
